For me, there's a viscious circle at work here. I don't use my phone that much because the usability is rubbish, and when I do I find it an exercise in frustration. So, when someone asks me to make a website usable on mobile, I really have no idea what usably on mobile would actually involve. And the result is I make a single column of content which is 100% of screen width and has all the buttons and text inputs enlarged. I've tried looking for advice about this on the web, but because mobile is such a hype-driven area, the search engine results for any mobile web design topic are inevitably marketing idiocy. So, where can I read something by people who've done real usability experiments on touchscreens?
